Through the Long Gap: Part I

It's been a very busy time here -- plannning, preparing for, having, and cleaning up after a birthday party, and also painting T's room so we can make it a cooler place to be. The room is mostly put back together now, and just waiting for the supposedly-VOC-free paint to outgas and stop stinking before we have T sleep in there again (he's camping out in my bedroom.) The walls look great. The kids got to help when they wanted to, learning bits about painting and putting together Ikea furniture. Now to document some of the other learning that's been going on....

There's been a lot of social learning. The kids play together a lot, and pretend play is usually their default activity if nothing else is suggested to them. They also seem to metabolize most of what they learn from outside sources (books, videos, situations we encounter together) through pretend play. That means there are LOTS of opportunities to have interactions with each other go well or poorly. Flexibility is key; I've told P about the rule in improvisational theater that you try not to act in a way that shuts off someone else's idea, but instead adopt an attitude of, "Yes, and...." She and T are both getting better at this kind of flexibility. Can there be lava in My Little Pony? Can there be two of the same character in a game? Increasingly, the answer is some form of, "Yes, and...." Sometimes when one of them is digging in heels at the other's suggestion, if I'm nearby and see it starting to happen, I'll say something like, "I think you have a big enough imagination to handle that, don't you?" That often gets things back on a cooperative track. Sometimes one doesn't directly concede the other's point, but comes up with a way around it. T and P were both wanting to play the same My Little Pony character, but P didn't want that, so she came up with her own original MLP persona (with her own name, colors, and "cutie mark," natch) that she can be if T wants the same character she does. It worked, releasing the tension and letting the game go on. They, and I, are learning to find the yes in as many situations as we can. (Part of this idea also comes from Sandra Dodd's writing and web pages; here's one about saying yes.)

We're also looking at competition, friendly and otherwise, and how it affects our relationships. Are we racing? Does everyone have to be racing for it to really be a race? If only the winner was racing, how does their gloating affect the rest of us? One way the kids argue about racing is getting buckled into car seats when we're getting ready to go somewhere. I wanted to head off the same old argument one day as we got ready to go, so I made up a song on the fly, to a raucous western-ish tune:

     No one wins, but everybody wins, when we work together
     No one wins, but everybody wins, when we're on the same team
     When we work against each other, people win or lose
     So there's one thing we get to do: We all get to choose
     'Cause no one wins, but everybody wins, when we work together
     No one wins, but everybody wins, when we're on the same team

Like most of my songs, it was pretty ad hoc, but it hit a nerve for the kids. They've been requesting it a lot and singing it themselves, especially when things are getting a little more tense and competitive than they're comfortable with. They understood my suggestion that, really, our goal was to get going, so we all won once we were all buckled in, regardless of who finished first.

In other social happenings, P now has a good friend at park days, one of the girls whose fairy house P added a tornado shelter to on that first good day. And I've been gratified that P has asked for, and taken, my advice several times recently. Sometimes she listens to my reasoning and still chooses something else, but she asks and listens, and I like that.

There's been a lot of reading. Some examples:
  • I picked up The Authoritative Calvin and Hobbes for twenty cents at a library sale a while back. Recently P picked it up and read it for hours on end.
  • UnschoolerDad order a book of the collected Copper web comics. When it came, P picked it up and read it all evening.
  • When I've brought home library books and at other times, P's been reading picture books to T a lot, and both of them are enjoying it.
  • One night, P stayed up very late and read an entire Magic School Bus chapter book about butterflies.
There's been a fair amount of watching of interesting videos, long and short:
  • We watched a Nature program about raccoons. This happened in two sittings, because once a family of baby raccoons appeared for a few minutes in the program, the kids were off to play baby raccoons. In the second sitting, we heard how urban raccoons may be evolving for more sophisticated brain development, as the urban environment gives them ever more challenging situations to respond to.
  • We (mostly P and I) watched a NOVA program on genetic testing and genomics. The program covered techniques and ethics of embryonic screening; how some genes determine disorders while others only influence their probability of occurring; how some people choose not to find out about the risk-factor genes, since the influence is fuzzy enough that they'd rather not know; how some people choose to get tested for things like the Huntington's gene so they can plan their lives accordingly and make appropriate financial plans; the structure of DNA and how single mutations or multiple copies of a sequence can cause problems; how DNA specifies proteins, which do most of the body's work; and more. Experimental drug therapies for melanoma and cystic fibrosis (CF) were described, along with patient case studies and the mechanism of failure in CF. I talked with P about how I got tested for the CF gene before getting pregnant, but since I was negative, UnscoolerDad (UD) didn't get tested, which means P may want to get tested before having kids in case she has a CF gene copy from UD. (We also talked about how, since genetic science and technology is progressing so fast, she may face a whole different set of tests and choices than we did.) When P was listening to the part of the program about mutations, she remembered a set of monsters in World of Warcraft called Mutated Owlkin; these monsters are found in an area with lots of radiation.
  • We watched the first part of a NOVA pragram about tornadoes; perhaps we'll watch the rest another time. It covered Doppler radar, and how you can use it to see the hook shapes in a thunderstorm that indicate a tornado may be forming. It also had great graphics of the jet stream and other weather patterns that contribute to tornado formation. We talked about duck and cover, and where the safer places are to be in a tornado.
  • We watched part of a PBS program about industrial agriculture. The first part of the program was very gee-whiz positive about all of it; unfortunately P got interested in something else just as the program started to get around to environmental and health consequences. Maybe we'll finish it soon! 
  • Both kids asked the same question within a day of each other: Are lions nocturnal? This led to a YouTube exploration of lions hunting, elephants helping each other out of a water hole, keepers moving an elephant to a new zoo exhibit nearby that we hope to visit, people taking a behind-the-scenes visit with two zoo hippos, and many other animal things. It turns out, by the way, that lions sleep about 20 hours out of 24, and their few active hours occur during both night and day.
Since it's been so long since I got anything out on this blog, I'll write up the rest of my notes (writing, economics, math, computers, etc.) in another post. But to wind up this one, here's a quick note on where my online time has been going instead of to this blog: Partly I'm playing World of Warcraft, with P or on my own; but lately I'm brushing up my Spanish and beginning to learn German on DuoLingo, a translation and language-learning project I encountered in a TED talk a while back that's still in the beta phase. T likes to listen to the audio that DuoLingo puts out and ask what each sentence means. P wants to try using it to learn Spanish, so I've put her on the list for a beta invitation. I tried LingQ a while back, but I didn't find it as engaging as DuoLingo has been so far, and trying to start a new language (Mandarin) on LingQ was a total fail for me; I just couldn't get a toehold. DuoLingo seems to have a better approach for a cold start on a language, though I've done enough singing in German that I can't quite say I'm starting from nothing; and of course having most of the alphabet in common between English and German is a huge help, compared to Mandarin. But aside from software comparisons, the most fun thing I've learned while playing with DuoLingo is that I do just fine working on two foreign languages at once. It might even make both go better. I used to think I had only one foreign-language spot in my head for a given word or concept in English, but it turns out there's more capacity there than I thought.

Road Trip!

Here we go with some things we learned and experienced on our family road trip! I made zero notes during the trip, so this is sure to be missing things, but here, at least, are some highlights.

We started off with a lot of driving, since we were headed through some very sparsely populated areas of New Mexico with not much to stop and see. On the way, both kids were interested in looking at maps of where we were going, which our road atlas provided. We brought out some electronic toys we'd bought for our last road trip two years ago, which played games for learning letters, shapes, phonics, and a little spelling. T didn't remember them, and they fed his current interest in letters, the sounds they make, and how words he knows are spelled (he'll look at a stop sign and ask, "How you spell stop?"), as well as a general interest in gadgets. Though P's already learned most of their lessons, she liked playing with them and helping T learn to use them.

And honestly, they fought over them quite a bit at first. Road trips are crucibles for dealing with squabbling and conflict in general, and the first full day on the road (we got away mid-afternoon the first day) was pretty rotten. One thing we learned was to put the toys away in the morning, when the kids were fresh -- interestingly, this brought no objections from the kids -- and look out the windows and talk together, or occasionally listen to a book on CD together. In the afternoon, when the kids started to wilt, we'd have some quiet time so T could take a nap (P would read, doze, look out the window, or write a note to a friend at home), and then if we were still driving after the nap, we'd get out the electronic toys -- with an agreement about how to share them -- or a video both kids could watch. We loaded up the iPad with episodes of the kids' favorite PBS Kids shows, and the ones that got the most love on the trip were Martha Speaks (lots of fun vocabulary development and storylines the kids enjoyed), Wild Kratts (an adventure show about animals and their "creature powers," which has led to some very detailed pretend play about being draco lizards, monarch butterflies, bats, etc.), and Dinosaur Train (which mixes time-traveling fantasy and family-oriented stories with lots of real information about dinosaurs, including some that's new to me).

Besides shaping the day to the kids' energy levels, the best thing I figured out to do was to ask the kids to think, in the morning, about what kind of day they wanted to have. (This was particularly fruitful after that first rotten day!) I'd remind them that what we all did would set the tone for the day, and encourage them to think about what they could do that would help make the kind of day they wanted to have. That, plus an occasional reminder that we all could affect how the day went, made a big difference toward compromise, peaceful conflict resolution, and general not-yelling-at-each-other. Other good developments in getting along: P got a little better at remembering she's not the only one in the family with desires and needs and trying to think of or agree to win-win or at least compromise solutions. For one specific example: Before the trip, P said she didn't want to share a bed with T at all, even though we might be getting some two-queen rooms for the whole family in order to pay for one room and not two. So we brought a sleeping pad she (or T, if she could convince him) could use to sleep on the floor. When it came down to it, she decided to try sharing the bed, and both kids ended up enjoying the night and morning cuddling and the waking up happy together. Fortunately their needs for nighttime sleep are very compatible right now! After the trip she told me she'd like to share a big bed with T some more at home, and T has asked P to help him get down for his nap twice.

After lunch on the second full day out, we arrived at Carlsbad Caverns, our first big destination. We did the self-tour of the Big Room with the kids' version of the audio guide, since T was too young for the ranger-guided tours. The audio guide was more information than the kids wanted to digest, so I'd listen to it and give them the highlights. We learned about how the cavern developed in the first place, how its many decorations were formed, and the history of its exploration, including the first explorer (who began at age 16) and the first female explorers (teenage daughters of other expedition members). It was T's naptime, so we ended up carrying his slumbering body through the second half of the 1.5-mile hike -- quite a workout in 95% humidity, and we were profoundly glad for the occasional bench. The things that stuck with me the most about the caverns were P's awe and wonder at a still-forming feature (this was near the end of the walk, and she already knew enough to understand what she was looking at and marvel at how those tiny drops of water were creating such massive forms), and the fact that some 4500-year-old bat guano was probably the youngest natural feature of the Big Room.

We had a wonderful time in the Carlsbad Caverns bookstore, which fortunately we found before the gift shop. T found a deck of photos of animals that he enjoyed playing with in the car. P got a couple of picture books about the desert to peruse. And best of all, we bought a field guide to cacti and other arid-lands plants. For the next day and a half, as we drove through West Texas, this helped us learn new plants and find out a lot about them, as UnschoolerDad, P, and I read sections of the book aloud. Saguaros and other giant cacti, which we didn't see but read a lot about, are particularly amazing in their details. (Oddly, I found that twice the right name for a plant occurred to me, even though I didn't think I knew the plant's name, and since I was driving for this whole stretch, I hadn't opened the field guide. The plants were staghorn cholla and mesquite trees. I am 100% certain I didn't learn those in school! A friend guessed that I'd read enough about the Southwest, especially in Barbara Kingsolver books, that I'd stored the names away then without realizing it.) As we drove through burned and unburned areas near Carlsbad, it was interesting to see the differences: which plants survived the burning, and how things were re-establishing themselves in that dry and rocky land.

We spent a long day driving across more of West Texas, watching the slow change in vegetation from yucca and cactus to mesquite and cactus, with more and more live oaks as we approached Austin. At a rest stop, I got out a ball to kick around. P wanted to play catch, saying, "I don't know anything about soccer." I said we didn't need to play soccer, and that kicking a ball around could be a lot like playing catch, only with your feet, so she gave it a try. Soon we were defending trees and picnic grills as goals and dribbling the ball around with great glee, which was a good prelude to a nap!

In Austin, we visited with family and spent a lot of time outside in the beautiful weather. We took a sunset cruise one night to see the bats leave their roosts under the Congress Avenue Bridge. The guide shared lots of interesting information about the river, the bridge, and the bats. The bridge was redone in the 1980s to make it better for the bats. Whereas before it was inhabited by a motley crew of male bats, now its deep expansion-joint recesses are so attractive that the pregnant mama bats have kicked out the guys and made it their summer nursery, housing nearly 2 million bats. The bats like having room to drop, which they need to do to get flying -- bats rarely land during an evening of flying and feeding. We saw some of them drop, but the most amazing thing was their agility in flying around tight corners. These creatures weigh about the same as a nickel. The evolutionary engineering to get something so slight to achieve and endure such tight cornering boggles the mind. We also enjoyed hearing the audible portions of their vocalizations as we passed under the bridge, though some of the babies on the boat with us seemed pretty distressed, possibly by higher frequencies only they could hear.

While we were in Austin, P's uncle, a Half Price Books fanatic, chased down a copy of the third book in Lemony Snicket's A Series of Unfortunate Events, so P could continue reading the series to herself as we drove. She chose several other books while she was at the bookstore. After we got home, P told me one evening that she was ready to give away her Magic School Bus books (as she's already done with most of her Magic Tree House books). When I asked why, she said that she'd already read them, and that they were now below her reading level. When I asked what she wanted to be reading now, she answered, "You know, longer books with smaller letters." She's caught on to the industry indicators of intended reading level, all right! In the same evening of conversation, she told me offhandedly that she was reading Little House in the Big Woods to T. Did you hear that sound of my heart singing a little at the initiative and the sibling harmony, not to mention the advance in reading level? And she still begs some nights to stay up late and read. (We still draw a line, albeit a blurry one sometimes, on bedtime, since T wakes up early no matter when he goes to bed, and more sleep makes better days. P, who can sleep in after a late night, gets a little more leeway.)

Our time in Dallas brought more family visits and some interesting experiences and potential future experiences. The kids learned that my parents' dog was failing quickly from a recently-discovered, aggressive cancer. He had some good days while we were there, but had to be put down shortly after we got back home. This went right by T, who doesn't show any understanding of the concept of death yet. P was very solicitous with the dog while we visited, and had a very dark day the day he was put down. She remembers a cat we put down a few years ago -- an early start to her real-world experiences with death. She does, in fact, still want to keep fish -- I broached the subject, and she kept us researching for most of an evening about the kinds of fish we might start with. I have the feeling there will be further experiences with death along that path, but also a wealth of learning about small ecosystems, water chemistry, predation, life cycles, and more.

We also visited my only living grandparent, my dad's mom, who gave me my choice of a wealth of genealogical records and photo albums to bring home. (She would have given me all of them, but space in the car was limited!) I tried to choose some that would provide many stories I could share with her and with the kids, so there should be some fun glimpses of history to be had there. P has enjoyed stories I've told her so far from family history gleaned on my mom's side of the family.

T and I had a quick adventure one afternoon in Dallas, riding the newish light rail system. One-on-one time with the kids is a blessing when it comes; T has so many more questions when I'm alone with him than at other times, and I like being able to go at his pace more of the time.

On the way back from Dallas, we stopped in Wichita Falls and checked out the River Bend Nature Center. It was a slow morning there, and the kids got a lot of attention from a volunteer, who took out several snakes for them to see and touch and told them what she knew about these particular snakes. There was a milk snake (a species often confused with coral snakes), and we learned the rule that if red touches black, that's a nonvenomous milk snake, but if red touches yellow, that's a coral snake and deadly. There was also a snake in for rehab who was not being handled, so we talked about the different reasons an animal might be in a nature center, and why different reasons would mean different treatment for the animal. We played outside on some covered wagons, noticing the springs under the seats and how they worked and relating this to the lack of shock absorption in the wheels and axles. There was a sandbox with lots of real bones buried in it; these seemed to be mostly horse bones. We dug up one or two dozen bones, noticing the shapes of the jaw bones, the porous and networked texture of all the bones, the shapes of the molars, and how some of the shapes made good digging tools. We talked about what sorts of tools people might have made from bones like these. We articulated a femur and pelvis that seemed to belong together, checking out the ball-and-socket joint with hands on and envisioning the ligaments that would hold the joint together in a live animal. We also went over our experiences with bones, trying to figure out what color bones would be in a live animal, since the ones we were looking at were all sunbleached. And we talked about the phrases "long in the tooth" and "look a gift horse in the mouth" as they relate to horses' molars continuing to grow well into adulthood. Finally, we stopped by the pond and checked out the structures of lily pads, with their sturdy stems and clinging roots.

At the Nature Center store we bought a couple of books of Mad Libs, which were new to our kids. Within fifteen minutes back in the car, P had the more common parts of speech (nouns, plural nouns, verbs, adjectives, and adverbs) sorted out and was enjoying the random hilarity as we filled in the Mad Libs together and read them out.

We took a rest day in Amarillo, getting some down time hanging around the hotel room and then checking out the Kwahadi Museum of the American Indian in town. There we saw arrow and spear points made from stone; different kinds of flutes and shakers; animal pelts of various species, including faces and feet; different kinds of beads and beadwork; people in the process of designing beadwork and weaving on inkle looms; and youth practicing theatrical versions of ceremonial dances. All the people were part of a scouting program, and none were Native Americans of any description. (One of the scout leaders told us this; it wasn't just our assumption based on appearance.) That felt odd to me, and made us wonder how faithfully things there were interpreted; but it was an interesting time nonetheless.

The rest of our trip home was very unscheduled and ad hoc, which was delightful. We stopped when something looked interesting and when it seemed a stop might be nice. An unassuming little museum in Dumas, TX, turned out to be a gold mine of artifacts from 100 years ago, give or take a decade or two. It was set up in many small areas, each focused on a different area of life or a different trade or business. We saw and talked about an old phone switchboard (we discussed how calls were connected then and now), a check cancelling machine from a bank (how checks work), a dry-goods store display with fabric and trims for clothing (similarities to modern fabric stores and the limited selection long ago), a doctor's office with herbal remedies as well as early pharmaceuticals and an ether-based anesthesia machine, a Victrola (P saw a vinyl record and asked, "What's this?" and we talked about what it was and how it worked, and I felt old!), a set of McGuffey readers (we discussed how few books an early schoolhouse would have had, and how students learned many subjects by reading and memorizing in these readers), a wall of post office boxes, a huge collection of toy and real tractors and other farm implements, and a shelf of court docket books, among a great many other things. I bought a pocketknife for P, who I think is ready for one -- I was reminded by Gever Tulley's TED Talk, "Five Dangerous Things You Should Let Your Kids Do," that I was already whittling at P's age, and didn't quite manage to put out my own eye doing so. Later that day I showed it to her, and we started on some verbal safety lessons about where and how to use it safely, including an account of my near-blinding experience. The hands-on lessons haven't begun yet, but she's eager to start, so we will soon.

We stopped in a few places in southeastern Colorado. One was a ranger station for the Comanche National Grasslands, where T and P scored a lot of free goodies from the friendly ranger staffing the counter. The best: a field guide to prairie birds, which P has spent a lot of time with since then. Sometimes she's reading it or incorporating it into pretend play ("This is a packet showing all the birds I sighted this morning on my birdwatching expedition!"), and sometimes she's relating it to birds she has seen. Another stop was a railroad depot in Kit Carson, where the museum was closed, but the kids still enjoyed climbing on a real caboose parked by the parking lot. The scale of a real train car is hard to fathom until you stand right next to it, and they finally had that opportunity.

And then there were things that happened all along, or didn't depend much on where we were:
  • We kept track of the numbers of engines and cars in each train we saw, if someone was available to count them at the time, and we worked out the ratio of cars to engines for each, using mental arithmetic and sharing a few estimation tricks with P. All the ratios came out between 30 and 35, regardless of the type of train or whether its cars were loaded or empty, except for one train that was stopped and looked like it might be in the process of being reconfigured. 
  • We watched The Weather Channel and Animal Planet several evenings in hotels, since it seemed to hold the kids' interest better than other available fare. We saw lots of riveting stories about tornadoes, floods, venomous snakes and lizards, invasive foreign animal species, and more, but even these lost their shine after a while. This was one of the first experiences our kids have had with broadcast TV and the idea that "what's on" is limited and often not that interesting. This almost feels like a history lesson, given all that's available on demand now!
  • We talked a little about caffeine as both a common stimulant and an addiction. When I explained once that we were stopping so UnschoolerDad could get some iced tea, P asked why he wanted it, and I  explained that he had been using it enough that he was getting some withdrawal headaches without it. P immediately asked the right question (to my mind): Why did he start using it in the first place? He had some good reasons, but P came away with what seems to me like a healthy suspicion that using habit-forming substances may not always be worth the short-term pleasures or benefits.
After we got back, P volunteered one day, "Sometimes I think I might want to go back to school, but then I think about it." I asked, "What thought stops you from leaning that way?" She replied, "I like being able to go places and learn about stuff I'm interested in."

And mama smiled.

Faith in the Process: Conversations and Continuity

Sometimes with this unschooly approach to learning, it feels like a huge assortment of stuff gets presented, or discussed, or looked at once or twice, but it's hard to tell what's sinking in. It reminds me of the anti-drug ad that shows a teen's face looking exactly the same before and after her parents talk to her about drugs. OK, P's not that opaque at 6. But still, sometimes it seems information goes in one ear and out the other.

And then it doesn't, and I see the links among bits of knowledge forming and getting used, and interest returning to related themes again and again, and my faith in this process of interest-driven learning returns.

A recent example: P has probably finished a sentence about a scientific or historical subject three times for me today, using knowledge I didn't know she had. How did she learn all this stuff? From Magic Tree House and, even more so, Magic School Bus chapter books. She has been rereading her moderately large collection at two books per day this week, which at first made me feel guilty for not finding her more good chapter books yet. But I'm noticing that the ones she's been rereading are providing a lot of the knowledge that gets mapped into other situations. So I will get her more (or put them on her birthday list for others), but I won't be in such a rush!

By the way, her reading skill is coming along beautifully. She wanted to read to me the other day from a Magic Tree House book about dinosaurs, and while she stumbled over Cretaceous and Pteranodon, her oral fluency with the more ordinary vocabulary was almost as good as mine -- which, I think can honestly say, is saying something! She's also getting much more accurate than she was a month ago at using punctuation clues to read dialogue with correct expression and intonation. I love watching her soar.

Saturday evening I took P to a friend's choral concert. On the way to the concert (a 45-minute drive), while waiting for it to begin (it was held in a Congregational church; we are Unitarian-Universalist), and on the way home, we talked about at least the following, and probably more that I don't remember:

  • Some possible reasons cats may be linked with witches in popular lore (One of my guesses: cats have been considered good luck at births because they give birth with apparent ease compared to human mothers; female healers, who would have assisted with births and who were later painted as witches when men started trying to take over medicine, may thus, or for other similar reasons, become associated with cats. I don't know whether this is the case, but cats-birth and women healers-witches are definitely associations that have been drawn at various places and times.)
  • Where it's safest to be in a lightning storm; lightning rods and how they can protect buildings and their occupants
  • How people get red hair; recessive genes; children get half their genes from each parent
  • Ways of ending up with a child without having it yourself (adoption, foster care)
  • What it means to be gay or lesbian (the chorus had a large number of GLBT members, and the friends who invited us are a gay couple with a child who came to them through the foster-to-adoption process)
  • Why there were bibles in the pew racks
  • What the little round holes in the pew racks are for (individual communion cups, which led to the story of the Last Supper and how Christian churches of various stripes practice communion, and why some non-Christian churches, like ours, have communion as well)
  • Other stuff in the pew racks: prayer request cards, envelopes for cash offerings... only the envelopes and the hymnals have close analogues at our church, so this was all fascinating stuff
  • Speed limits: why they exist, why they are enforced, why people exceeding them slightly don't generally get ticketed
  • Why infants ride in backward-facing car seats, why we don't all ride facing backwards

Today I showed P a photo one of my friends, who is a midwife, posted on Facebook, showing her tending to a newborn baby. P asked, "Did she bring a cat?" We talked about the likely answer (probably not, though she probably would have no problem with the family's cat being there for a home birth), but I loved the continuity of ideas, considering that I didn't even mention the word midwife in the earlier conversation. P remembered it because three years ago, when T was born, a nurse-midwife at the hospital was our main caregiver during pregnancy, labor and birth. Also today, P said something about blue jeans and then noted aloud that jeans is a homonym. I asked her other meaning she knew, and she talked about the genes that come from both parents to make a baby. Hooray!

Also this week, we listened to Sadako and the Thousand Paper Cranes on tape. We've been talking a little about nuclear weapons and radiation in the context of the current nuclear troubles in Japan, so this was a natural extension. Sadako's leukemia also tied back to our recent conversations about cancer.

And today, we found our first letterbox! (Look here for a short description and lots of links about letterboxing.) We hiked about a mile round-trip on rocky trails near the National Center for Atmospheric Research. Before setting out, we visited the NCAR lobby, which has lots of displays, some of them interactive, about atmospheric science and the tools it uses. Along the way, we identified some plants (yucca, juniper) and talked about their defenses against getting eaten. On the way back, we stopped and read several signs on the NCAR weather trail about floods, droughts, fires (one of the sentences P finished for me was about fire suppression leading to more intense forest fires, whereas allowing fires to burn and just protecting structures can lead to healthier forests), lightning, and erosion. We examined the anemometers and wind vanes atop the NCAR roof and talked about what they measured and how, and whether any of those other things up there were lightning rods. We read signs about trails that were closed, some for revegetation and others to protect nesting raptors and breeding bats. We marveled at the view from the NCAR terrace, where we ate part of our picnic lunch. It was a beautiful hike and a rich learning experience, and the kids loved the "secret mission" feel of finding and re-hiding the letterbox. That the 1-mile hike took us an hour and a quarter may give you an idea of the walking:learning ratio.

I think letterboxing, pursued at a leisurely pace and with lots of side trips, is going to be a great way for us to get out and see new places and things. And P wants her 7th birthday party, which will happen next month, to be a letterboxing party. Now that's a party I can have fun helping prepare! We'll hide boxes with hand-carved stamps and logbooks around our yard and possibly in cooperative neighbors' yards. We'll help each guest create his or her own unique signature stamp. We'll prepare puzzle clues so each child can play a part in working out where to find the boxes. It's a win-win-win: we make a fancy treasure hunt with a low budget and a theme that may introduce other families to a cool new hobby, P and I will get to create puzzles together, and I'll get to practice my stamp carving!

Even more stuff: P and I watched the last of the Jim Henson: Storyteller Greek myth episodes, which was the story of Perseus and the Gorgon. I think the most interesting discussion we had about that was about Acrisius' attempt to prevent Perseus from killing him, as the Oracle predicted. He imprisoned Danae, and then after she bore Zeus's child anyway, he had mother and son locked in a treasure chest and thrown into the sea. They lived, and Acrisius was eventually killed in an accident, by a discus Perseus threw in a competition Acrisius attended, before the two could become reacquainted. The theme of fate being inevitable, of disaster avoided on one path returning by another (cf. Oedipus the King), is so clear here.

Oh, and never fear, T is learning too! He can talk about more things and show more of what he knows all the time. Today we found a Brain Quest deck of questions and answers for 3-4 year olds (T recently turned 3, but these were from when P was little), and he and I had fun going through it and seeing how much knowledge and cognitive skill he has picked up in his short and late-to-speak life. There's no shortage of candlepower there. But I write more about P -- partly because no school district yet has the right to ask me to account for T's learning, but they could do so for P -- and partly because P just talks so much more about, well, almost everything except helicopters, motorcycles, and construction machinery.
